Design and Simulation of Indigenous Roll-over Sensor for Four-Wheeler Automobiles

Piyush Raj [1], Adarsh G Datta [1], Vishnu Kumar [1],
[1] Indian Institute of Science, Bangalore, Karnataka, India

In India, more than 150,000 people are killed each year in traffic accidents, according to the Ministry of Road Transport and Highways 2016 report. That’s about 400 fatalities a day, which is far higher than in developed auto markets like the US which, in 2016, logged about 40,000 a ... En savoir plus

Numerical Simulation of Coupled Fluid-Solid Interaction in Digital Rock Samples

V. Das [1], T. Mukerji [1], G. Mavko [1],
[1] Stanford University, Stanford, CA, USA

Digital rock physics (DRP) is an emerging field where a rock sample is imaged, relevant physical processes are simulated numerically on the digital rock sample, and the numerical solutions are used for understanding and interpreting the rock in different in-situ conditions. The use of ... En savoir plus

Application of Solution Mapping to Reduce Computational Time in Actively Cooled Power Electronics

K. Lowe [1,2], and Rao V. Arimilli[2]
[1]Oak Ridge National Laboratory, Oak Ridge, TN, USA
[2]Department of Mechanical, Aerospace, and Biomedical Engineering, University of Tennessee, Knoxville, TN, USA

In some power electronic applications the available coolant temperature is close to maximum and controlling operating temperature becomes more challenging, for which new thermal management schemes must be considered. COMSOL predicts the 3D fluid behavior and 3D temperature distribution ... En savoir plus

Numerical and Experimental Study of Flow, Heat Transfer and Concentration in a Scaled-up Fuel Cell Anode Channel Model

J. C. Torchia-Nüñez[1], and J.G. Cervantes-de-Gortari[1]

[1]Department of Thermal Engineering, National University of Mexico, UNAM, Mexico City, Mexico

Flow, concentration and temperature fields are studied with numerical and experimental methods inside a scaled-up fuel cell anode channel model. The low aspect ratio channel has a porous medium as the inferior wall where a mixing of different pH solutions occurs. Chromatic change of ... En savoir plus

Modeling of a Vapor Chamber Using COMSOL Multiphysics®

Melissa Rodriguez Vargas ¹, Bruno Chiné¹
¹School of Materials Science and Engineering Costa Rica Institute of Technology, Cartago, Costa Rica

High power consumption chips have already become a major challenge for modern processors causing low thermal performances. Existing thermal solutions are not able to solve these high temperature issues efficiently. Two-phase cooling devices such as heat pipes and vapor chambers have ... En savoir plus

FSW Quality of Inconel 718: Numerical Modeling and Fuzzy Logic-Based Temperature Control Approach

Mohammed Al-Azba¹, Ahmed Abotaleb², Yves Remond², Said Ahzi²
¹Hamad Bin Khalifa University, Doha, Qatar
²ICube Laboratory, Université de Strasbourg-CNRS, 67000 Strasbourg, France

Friction stir welding (FSW) is a revolutionary technique for joining high-strength materials, offering superior mechanical properties compared to traditional fusion welding methods. However, achieving optimal surface quality in FSW of Inconel 718 is challenging due to the material's ... En savoir plus

Simulation of Magnetically Driven Peristaltic Pumps for Microfluidic Applications

L. Gritter [1], J. Crompton [1], K. Koppenhoefer [1], P. Nath [2]
[1] AltaSim Technologies, Columbus, OH, USA
[2] Applied Modern Physics, Los Alamos National Lab, Los Alamos, NM, USA

Microfluidic technologies can enable laboratory processes to be packaged in miniaturized and automated systems, allowing these processes to be performed with hand-held devices outside a laboratory environment. The practical usefulness of these “lab on a chip” systems has often been ... En savoir plus

Thermal and Flow Simulation of a High Temperature Printed Circuit Heat Exchanger

Q. Zhu[1], X. Tan[1], B. Barari[1]
[1]MIT, USA

Printed circuit heat exchanger (PCHE) is a key component in many energy and power systems, such as concentrated solar power plant, nuclear power plant, aircraft, etc. In this paper, the thermal and fluid performance of a lab-scale PCHE is analyzed using COMSOL Multiphysics® simulation ...

G. Petrone [1], C. Barbagallo [1],
[1] BE CAE & Test, Catania, Italy

An app built with the COMSOL Multiphysics® software allows both expert and beginner users to carry out parametric simulations thanks to flexible and user-friendly customized interfaces. Many people, with or without expertise in numerical analysis, can now access, exploit and share ... En savoir plus

Geophysical Fluid Dynamics: Modelling Non-Linearly Viscous Ice-Flow to Obtain Dates of Flow Change

R. Hindmarsh[1]
[1]British Antarctic Survey and Durham University, United Kingdom

Ice flows because at low stresses it deforms viscously; the viscosity depends upon the stress. The lubrication approximation (LA) states shear stress is proportional to the product of the ice depth and surface slope. At ice divides the slope and shear stress are zero meaning the ... En savoir plus
